Unauthenticated File Read via Browser Authentication Bypass

CVE-2026-48133 affects Check Point Security Gateways when the Identity Awareness blade is configured with Browser-Based Authentication enabled. This vulnerability allows unauthenticated attackers to bypass authentication mechanisms and read sensitive internal files directly from the gateway, potentially exposing configuration data, credentials, or system information. Organizations deploying Check Point appliances with identity-aware security policies are at risk, particularly in environments relying on browser-based authentication as a primary security control. The 7.5 CVSS score reflects the significant impact of unauthorized information disclosure without requiring authentication or user interaction.

While this CVE does not map to specific MITRE ATT&CK techniques, Casky's security skills would help practitioners identify reconnaissance and lateral movement patterns associated with file access anomalies. Through Claude's extended reasoning capabilities, defenders can correlate unauthenticated web requests to the Security Gateway, unusual file-read patterns in gateway logs, and early indicators of authentication bypass attempts—even before exploitation succeeds. Practitioners would observe findings highlighting suspicious unauthenticated HTTP requests targeting internal file paths, absence of valid authentication tokens paired with successful responses, and deviations from normal Identity Awareness blade behavior. These behavioral indicators enable security teams to detect attempted exploitation and implement mitigations before sensitive data exposure occurs.
